A thermal latent acid catalyst which comprises (i) a compound having an epoxy group, (ii) a compound having a sulfur atom of the following formula: R5-S-R6, wherein R5 and R6 are the same or different from each other and are a hydrogen atom or an organic group of 1 to 40 carbon atoms, R5 and R6 optionally are bonded with each other to form a cyclic structure; and (iii) a Lewis acid of the following formula: (X1)n1-M1-(R7)n2, wherein M1 is a boron atom, an aluminium atom, a tin atom, a lead atom or a transition element, X1 is one or more halogen atoms, R7 is one or more organic groups of 1 to 40 carbon atoms, R7 optionally forms a chelate ring by coordinating to the M1 atom, n1 and n2 are each an integer of 0 through 6, and n1 plus n2 equals an integer of 1 to 6. The ratio of the epoxy group of the epoxy compound (i) to the M1 atom of the Lewis acid is 0.2 to 10 and the ratio of the sulfur atom of the compound (ii) to the M1 atom of the Lewis acid is 0.2 to 10.
